Mark for Model Number RTW4640YQ1 Hello Sirs: Thank you for the tech sheet. When I entered the Fault Code Display Mode, it showed the error code "F7E1". I followed the instruct, entered the Manual Test Mode, "Heavy Agitation" test is always past, the "High Spin" test was always failed and "Low Spin" test was sometime failed, after I entered the calibration mode, "Low Spin" test was past. But sometime the "Low Spin" test was failed again. Do you have any suggestion? What issue it maybe? Thanks.
Answer Mark, it would be recommended that the motor WPW10677715 windings are tested for resistance. At the main control connection J16 from the wire at pin 5 to the wire at pin 6, there should be a resistance between 5O to 9.5O. Then from the wire at pin 5 to the wire at pin 7, there should be a similar resistance. If the motor tests good, then the shift actuator WPW10006355 would need to be tested from the main control at connection J2. With the washer turned on, the red meter probe will go to pin 4 and the black meter probe to pin 3 and there should be a 13VDC reading. If there is 13VDC, the next step would be to activate the tachometer test in diagnostics and rotating the spin basket by hand slowly. This should cause the LEDs to illuminate one at a time to represent basket RPM. If there is not 13VDC or the LEDs do illuminate one at a time, it would likely be that the main control W10484681 failed. If the LEDs do not illuminate one at a time, it is likely that the actuator has failed. Read More... Answered by AppliancePartsPros.com | Tuesday, August 4, 2020
